David Brown 3f9ec900c4 zephyr: Configure mbed TLS for PSS instead of V1.5 
Although MCUboot has used PKCS#1 v2.1 (PSS) for some time now, the mbed
TLS config file was calling out v1.5.  This compiled because MCUboot
implements its own specialized version of the signature check, and only
needs the underlying primitives from mbed TLS.  (The general code in
mbed TLS is quite a bit larger).

To make it clear that we are always using PSS, change the mbed TLS
configuration to call this out explicitly.

Coverity Scan Build Status Build/Test

This is mcuboot, version 1.1.0

MCUboot is a secure bootloader for 32-bit MCUs. The goal of MCUboot is to define a common infrastructure for the bootloader, system flash layout on microcontroller systems, and to provide a secure bootloader that enables easy software upgrade.

MCUboot is operating system and hardware independent, and relies on hardware porting layers from the operating system it works with. Currently mcuboot works with both the Apache Mynewt, and Zephyr operating systems, but more ports are planned in the future. RIOT is currently supported as a boot target with a complete port planned.

Using MCUboot

Instructions for different operating systems can be found here:

Roadmap

The issues being planned and worked on are tracked on Jira. To participate please visit:

Browsing

Information and documentation on the bootloader is stored within the source, and on confluence:

https://runtimeco.atlassian.net/wiki/discover/all-updates

For more information in the source, here are some pointers:

  • boot/bootutil: The core of the bootloader itself.
  • boot/boot_serial: Support for serial upgrade within the bootloader itself.
  • boot/zephyr: Port of the bootloader to Zephyr
  • boot/mynewt: Mynewt bootloader app
  • imgtool: A tool to securely sign firmware images for booting by mcuboot.
  • sim: A bootloader simulator for testing and regression
